Trial Summary

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What data supports the idea that Zirconia Crowns for Tooth Decay is an effective treatment?

The available research shows that Zirconia Crowns are effective for treating tooth decay in children. They are praised for their aesthetic appeal, which is important for both children and parents. One study followed a child with a zirconia crown for 29 months and found that it provided a natural look and maintained good gum health. Another study reported that zirconia crowns stayed in place well and looked good over a 30-month period. These crowns are also easier to place compared to other options, making them a practical choice for restoring decayed teeth. Overall, zirconia crowns are a promising alternative for treating decayed primary teeth, offering both functional and aesthetic benefits.12345

What safety data is available for zirconia crowns in treating tooth decay?

The safety data for zirconia crowns in treating tooth decay includes several studies and reviews. A systematic review evaluated clinical, child, and parental satisfaction with zirconia crowns in maxillary primary incisors, highlighting their aesthetic benefits and ease of placement. A prospective cohort study assessed the 5-year survival and success of anterior maxillary zirconia-based crowns, although it noted limited studies in this area. A 29-month follow-up study of a pediatric zirconia crown on a deciduous molar reported sustainable functional restoration, good adaptation, gingival health, and minimal wear on opposing teeth. A retrospective cohort study evaluated the marginal integrity, gingival health, and aesthetics of zirconia crowns on primary maxillary anterior teeth over follow-up periods ranging from 6 to over 30 months. These studies collectively suggest that zirconia crowns are a safe and effective option for restoring decayed primary teeth, with positive outcomes in terms of aesthetics and functionality.12567

Is the treatment Zirconia crowns a promising treatment for tooth decay in children?

Yes, Zirconia crowns are a promising treatment for tooth decay in children. They offer a natural appearance, are easy to place, and have shown good retention and aesthetic results over time. They are a practical and effective alternative for restoring decayed primary teeth, addressing both functional and aesthetic needs.12348

What is the purpose of this trial?

The purpose of this research study is to test the effectiveness of two different crowns/caps on teeth for restoration of primary anterior teeth. The two different materials of crowns are esthetic crowns with retentive grooves and without retentive crowns. These crowns are placed on the teeth to restore function, esthetics and prevent further caries and infection.

Treatment Details

Interventions

  • Zirconia-based primary anterior crowns without retention grooves
  • Zirconia-based primary anterior crowns with retention grooves
Trial Overview The effectiveness of two different designs of zirconia-based crowns for front teeth is being compared. One design includes retention grooves that may help hold the crown in place, while the other does not have these grooves.

Findings from Research

Zirconia crowns are a highly satisfactory treatment option for decayed primary anterior teeth, with both parents and children reporting high levels of satisfaction based on a review of nine studies.
The studies indicate that zirconia crowns provide clinically acceptable restorations for maxillary primary incisors, but future research should involve larger sample sizes and longer follow-up periods to further validate these findings.
Evaluation of the Clinical, Child, and Parental Satisfaction with Zirconia Crowns in Maxillary Primary Incisors: A Systematic Review.Hamrah, MH., Mokhtari, S., Hosseini, Z., et al.[2022]
A zirconia crown was successfully used to restore a primary molar in an 8-year-old boy, demonstrating effective long-term functionality and aesthetics over a follow-up period of 29 months.
The study highlights the importance of proper implementation and maintenance protocols for zirconia crowns, showing that they can maintain gingival health and minimize wear on opposing teeth while providing a natural appearance.
Twenty-nine-month follow-up of a paediatric zirconia dental crown.Lopez Cazaux, S., Hyon, I., Prud'homme, T., et al.[2020]
Zirconia crowns provide an effective and aesthetically pleasing solution for restoring extensively decayed primary maxillary anterior teeth in young children, as demonstrated in a case study over a 30-month period.
The crowns showed good retention and functional results after endodontic treatment, making them a practical choice for pediatric dentists dealing with significant tooth structure loss.
